Yes the pumps are adding heat (mag drives? or what? what model/size?)
In general if you have 2 x 100W pumps then you have the same as 2 x 100W heaters running full time...

And the top is not allowing sufficient heat to be removed from the tank and potentially causing other "gas exchange" related issues...
An aquarium should never be completely sealed or even close to that. The water must "breathe" just like you and me..
